Answer / krishna
Methods are:
0) Class.newInstance()
1) ejbCreate()
2) setSessionContext()
3) ejbCreate()
Does Not Exist state & Method-Ready Pool are two status of the Beans
as per my knowledge Stateless Session Beans will not contain ejbActivate()& ejbPassivate() methods

To handle that event like call attented, call disposed and idle time they have give one event listener class.. I did every thing and this class is alsoo called when a particular event is fired. The only thing is i wanna call EJB from that event listener method.. But the EJB is not getting initated and exception is thrown. This below shownn error is occured only i try to call it from this event listener class.
